Universally movable mounting mechanism with locking and unlocking provisions and wherein the unlocking provisions are operable in accordance with operator feel

ABSTRACT

A universally movable mounting mechanism in which the mounting mechanism is connected to a fixed ball by spherically shaped friction cups which are spring biased toward one another to lock the mounting mechanism in fixed position on the ball and which can be selectively moved away from one another to either totally eliminate the friction between the friction cups and the ball to thereby free the mounting mechanism for universal motion in response to actuation by a pilot operated handle or in which the friction between the friction cups and the fixed ball is selectively reduced so as to maintain a desired mount positioning force in accordance with operator feel as he moves the mounting mechanism through handle motion.

6 Claims, 5 Drawing Figures UNIVERSALLY MOVABLE MOUNTING MECHANISM WITH LOCKING AND UNLOCKING PROVISIONS AND WHEREIN THE UNLOCKING PROVISIONS ARE OPERABLE IN ACCORDANCE WITH OPERATOR FEEL The invention herein described was made in the course of or under a contract or subcontract thereunder with Department of the Navy, Naval Air Systems Command.

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to the supporting or mounting mechanism for a camera or other viewing apparatus so that the mount can be moved to any selected position through universal motion, so that the mount can be rigidly locked in position, and so that the mount can be either fully or partially released for motion, and particularly to such a mount system wherein these functions can be performed by an operator using but one of his hands.

In some mount installations, such as helicopter night rescue missions, it is important that a direct viewing scope be utilized to locate object and that it be mounted so as to be positively locked in position so that its position is unaffected by aircraft vibration, by aircraft buffeting and maneuver motions and by accidental bumping by the operator. It is also important that the operator be able to control the amount of friction in the mount so as to assist him in accurately positioning and repositioning the mount.

2. Description of the Prior Art In the mounting art, cameras and other viewing devices have been mounted for universal motion by action of an operator control handle as in US. Pat. No. 1,780,383, but this prior art construction includes no provisions for selectively positively locking and unlocking the mount in position. Viewing apparatus have also been mounted for selective motion and locking about a given axis due to a trunnion connection between the viewing apparatus and the mount and have been handle actuated as in US. Pat. Nos. 2,667,321 and 2,886,276, but this does not provide the universal motion required by some installations.

SUMMARY OF INVENTION A primary object of the present invention is to provide an improved viewer mount which permits universal motion of the viewer, which positively locks the viewer in selected position such that very substantial forces would be required to dislarge the viewer so locked, and so that the viewer can be fully released for operator movement to any selected position or can be partially friction released so that the operator can move the viewer by overcoming a selected amount of friction the friction force between the friction cups and the ball to permit the operator to move the viewer to any selected position by handle motion.

It is a further object of this invention that the amount of biasing or friction loading between the friction cups and the ball can be preset and can be readily varied in operation.

It is a further object of this invention to mount the viewer so that there is a high velocity ratio linkage system between an operator actuatable trigger on the viewer handle and the viewer support release mechanism so that low force, substantial distance movement of the trigger will result in high force, minute movement of the release mechanism to give the operator a feel for the amount of friction remaining between the friction cups and the ball and which must be overcome by handle action to move the viewer to its next selected position.

It is a further feature of this invention that spring members of high spring rate, such as Belleville spring washers, be used to bias the friction cups to their locked position on the mounting ball. This high friction loading between the frictions cups and the mounting ball prevents motion of the viewer from its locked position due to vibrations, support motion and inadvertent bumping thereof, compensates for small machining inaccuracies in the mating parts, protects the mounted equipment when not in use, and compensates for wear between the mounting ball and friction cup.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG. 1 we see helicopter l0 hovering above a ground target and with a viewer 12 supported from support tube 14 which extends across doorway 16 of fuselage l8 and is shaped to extend outboard thereof. As an example of the type of function which the viewer mount can perform, it is being shown in this helicopter environment performing this particular rescue mission Other uses for this mount are also possible, such as for a gun sight. An operator stands at the viewer in the helicopter fuse-lage doorway and directs the viewer toward the ground, searching out the target, such as a downed military personnel. When the ground target is in view, it is necessary that the helicopter be brought to hover above the ground target and that a hook from conventional winch mechanism 19 be lowered accurately and quickly to recover the subject. Since the viewer operator is the person who can best see the ground target, it is necessary that the operator perform the functions of operating the viewer, operating the aircraft hover control and operating the rescue hoist control, simultaneously. These last two controls are conventional and form no part of this invention but in view of the fact that the single operator must operate all three mechanisms, it is essential that this single operator be able to selectively train, lock and unlock the viewer in position utilizing one hand, and this is an important feature of my mount system.

Viewing FIG. 2 we see viewer support mechanism 22 which is adapted to support viewing means 12 of FIG. 1 in conventional fashion, mounted on support tube 14. Support tube 14 is pivotally connected to doorway 16 of the helicopter by pivot pin assembly 24 which includes pin member 26 extending through forked legs 28 and of support tube 14, to thereby give support tube 14 and support mechanism 22 substantial support strength as it extends in cantilever fashion across doorway 16. Lock pin mechanism 32 locks the opposite end of support tube 14 in position to the opposite side of doorway 16. Accordingly, support tube 14 and hence support mechanism 22 are fixedly held in position with respect to the fuselage 18 of the aircraft 10 and support tube 14 is shaped or bowed to extend viewer support 22 outboard of fuselage 18. When the viewer is not in use, lock pin mechanism 32 can be released and the support tube 14, with the viewer support 22 still installed thereon, can be pivoted about pivot pin assembly 24 into a stowed position within fuselage 18 and locked in this stowed position by a mechanism similar to lock pin 32.

Referring to FIG. 3 we see my viewer support mechanism 22 .shown in greater particularity and supporting viewer 12 from support tube 14. Ball or spherical member 16 has pin member 38 projecting therefrom and passing through support tube 14 so as to be fixedly positioned therefrom by the coaction of nut or ring member 40 and nut member 42 which engages the threads on pin member 38. Accordingly, ball member 16 is fixed in position and supported by tube assembly 14 from the aircraft fuselage 18. We will see that all other portions of my support mechanism 22 are movable with respect to ball 16 and can be caused either to be locked in position with respect to ball member 16 or unlocked therefrom wholely or partially so that relative motion of a universal nature can take place therebetween.

Static friction cup member 44, which has a spherical inner surface 46 which matingly engages the outer spherical periphery of ball member 16, is positioned on one side of ball member 16. Movable friction cup member 48, which has an inner spherical surface 50, which matingly engages the spherical surface of ball 16, is located substantially on the diametrically opposite side of ball member 16. Bolt members 52 and 54 pass through appropriate apertures 202 in static friction cup member 44 and threadably engage support platform 56 so that, with the assistance of spacer sleeves 58 and 60, support platform 56 is supported in fixed and spaced relation to static friction cup 44. Annular and flexible seal member 66 extends between static and movable friction cups 44 and 48 to prevent foreign matter from entering the space between the friction cups so as to become wedged between the friction cups and ball member 16 to thereby adversely affect viewer operation.

Movable friction cup 48 has threaded stem 68 which threadably engages load adjusting ring or nut 70. Belleville spring washers.72 and 74 extend between the skirt of adjusting ring 70 and plate member of support platform 56 so as to impose a very stiff or strong spring load between adjusting ring 70 and support platform ring 80 and therefore between movable friction cup member 48 and static friction cup member 44, which are attached thereto, respectively. Belleville washers 72 and 74 therefore serve to bias the friction cup members 44 and 48 toward one another and into very heavy friction engagement with ball member 16. Adjusting ring 70 can be rotated to regulate this spring biasing force to establish both a preset force, and a force which can be varied readily during viewer operation since the skirt portion 75 of the adjusting ring 70 includes a series of peripheral apertures, such as 82, into which any lever member, such as a screwdriver, can be inserted to readily adjust the position of ring member 70 and hence the biasing or loading of the system.

It is important to note that with the cup members so mounted, the cup members are brought into locking engagement with 'ball member 16 directly and without any type of rotary motion therebetween. This is important because it saves wear between the friction cup members and the ball member.

It is necessary that provisions be made for releasing the viewer support platform 56 from ball member 16 and this mechanism will now be described and for this purpose reference is hereby made to FIG. 4. It should be born in mind that while a mechanical system is shown here, it will be evident to those skilled in the art that a hydraulic or an electromagnetic system could be substituted therefore. It is important, however, that the system have a high velocity ratio so that a low force, and substantial operator motion input results in high force, and minimal motion unlocking outputs at the viewer support mechanism 22. Handle projects from support platform 56 and has pistol grip 92 forming a part thereof so that the operator can grab pistol grip 92 with one hand and, with the support mechanism released from ball mechanism 16, can move the support 56 thereabout to any selected position. With the viewer in the newly selected position, the viewer mount is then locked in position on ball member 16.

To perform this mount locking and unlocking function, the operator utilizes trigger mechanism 94 which is connected to movable friction cup member 43 through a high velocity ratio linkage system 96. As used herein, the term high velocity ratio means that for a low pressure, substantial motion of trigger 94, a high force, minimum motion will occur at movable friction cup 48. Such a system could also be called a high lever advantage or high mechanical advantage system.

It will be noted by viewing FIG. 4, that trigger 94 is pivotally connected at pivot point 98 to pistol grip 92 for pivot motion thereabout and is shaped to engage pivotally mounted link or crank member 100 at end 102 thereof. Member 100 is pivotally mounted in handle 90 to be pivotable about pivot point 104 and includes a shorter am 106 extending therefrom to engage end 108 of lever 110. Lever 110 is pivotally mounted in viewer support platform 56 to be pivotable about pivot point 112 and so as to have long arm 114 projecting therefrom to engage link 100 and to have short arm 116 projecting therefrom to pivotally connect to movable friction cup member 48 at pivot joint 118. Due to the shape and selectively positioned pivot mountings of trigger 94 and levers 100 and l 10, trigger 94 has a lever advantage of 2:1, lever 100 has a lever advantage of 4:1, and lever 110 has a lever advantage of :1 so as to give an overall system advantage of 80:1. Removable pin 120 forms part of pivot joint 118 and connects lever 1 10 to movable friction cup 48.

It will therefore be seen by the pressing trigger 94 the operator can with one hand cause friction cup 48 to move away from ball member 16, thereby releasing support platform 56 from ball member 16 and the operator can then selectively position support 56 in any selected position by manipulating handle 90 as desired. With the viewer in its newly selected position, release of trigger 94 will permit Belleville washers 72 and 74 to force friction cups 48 and 44 into high friction engagement with ball member 16 once again, thereby locking the mount 56 and viewer 12 in position.

The importance of the very high lever advantage or velocity ratio of 80:1 described above is that a ten pound force imposed by the operator upon trigger 94 will impose an 800 pound releasing or unlocking force of movable friction cup 48 so as to overcome the biasing forces of Belleville washers 72 and 74. This 80:1 lever advantage is further significant in that any motion which the operator imparts to trigger 94 is reflected in one-eightieth of that motion at movable friction cup 48. This is highly significant in that the operator can very selectively and accurately impose any desired amount of force upon movable friction cup 48 so as to either completely or partially overcome Belleville washer springs 72-74. With the spring force partially overcome, the operator retains a selected amount of friction loading between the friction cups and the ball member 16 and he has a feel for the amount of friction loading remaining as he moves handle 90. This is very important to viewer mounting mechanism located in the vibrating turbulent environment of an aircraft.

Referring to FIG. 5 we see static friction cup member 44 in greater particularity. It is important to note that it has both a skirt portion 200 through which bolt holes 202 project to receive bolt members such as 52 and 54 of FIG. 3, and also includes spherical portion 204. Arcuate slot 206, which is normal to cup axis 208, is located within spherical portion 204 of the static friction cup 44 and extends a selected arcuate distance and is of selected width to receive stem 38. Stem 38 of ball member 16 passes through slot 206 along axis 208 so as to provide universal motion for the support platform or mount 56. It will be evident that with trigger 94 depressed, the movable portions of the viewer support mechanism 22, including friction cup 48 are movable about axis 208 to any desired angle and then movable with respect to ball 16 in an additional degree of freedom due to the relative motion which is permitted for stem 38 within slot 206.

[t is important to note that with our support platform 56 mounted on fixed ball 16, and operable through handle 90, all motions of the support and hence the viewer occur about a single geometric point, namely,

the geometric center of ball 16. Such a mounting is considerably of benefit to the operator in positioning the viewer since it is easier to position the viewer with this mechanism than it would be if the viewer were mounted for rotation about two different and spaced trunnions.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
